BRUSH-CYLINDER FOR SPREADERS, COTTON-GINS, &C.

Specification of Letters Patent No. 21,568, dated September 21, 1858.

To all whom t may concern:

Be it known that I, A. M. LANPHER, of Gloucester, New Jersey, haveinvented a new and useful Improvement in the Art of ConstructingMachines for Picking and Spreading Cotton and other Fibrous Substances;and I do hereby declare the following to be a clear and exactdescription of the same, reference being had to the annexed drawings,made part of this specification, and lettered to correspond therewith,similar letters referring to similar parts .in the several figures.

My invention relates to that class of machines which are used in cottonmills, for picking and spreading the cotton, as it is taken from thebales, and passed on to the rollers, preparatory to carding; andconsists in the application and use of a cylindrical brush, constructedand arranged as described, whereby the brush in combination with the sawcylinder, not only performs the oiiice of the willow, but that of thebeater and blower at the same time, without danger of setting fire tothe mill.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

Figure 2, in the accompanying drawings, represents a plan of theimproved picker and spreader, and Fig. l is a longitudinal verticalsection of the same, through the center line A, A, A, represent theframe work of the machine; I, I, are rollers over which the feedingapron passes when it conveys the unpicked cotton, or other fibrousmaterial, to the feeding rollers I, I; D, is the cylinder carrying aseries of circular saws whose teeth engage the cotton, as it passesthrough the feeding rollers I', I, and separating the fibers, carries itover until it is doffed by the revolving brushes arranged on thecylinder B; E', E', E, represent these brushes extending along the faceof the cylindrical frame work, and E, E, E, representbrushes arranged onthe ends of the same frame work, in radial lines nearly, and in adirection nearly parallel with the brushes on the face.

C, C, C are the brush frames, attached to radial arms, extending fromthe cylinder B; F, F, are wire cylinders, which are arranged as usual,for conveying the fibrous material to the spreader; K, K, the feedrollers; H, the beater; Z, Z, wire cylinders; K, K, K, K, the differentrollers, have nothing peculiar in their construction or arrangement todistinguish them from those in use in the common spreaders. But thebrushes E, E, E, arranged on the ends of the revolving cylindricalframe, are the distinguishing features of my invention; and constitutemy improvement in the brushes used for analogous purposes. It is wellknown to those who have used these revolving brushes in cotton mills andin cotton gins, that they frequently take fire from the friction betweentheir ends and the frame work; and so common has this accident become inthe mills, that it has become exceedingly difficult to obtain insurancewhile they were used. To obviate this difficulty was one of the endsaimed at .in my invention, therefore; and the other, was to prevent thefilaments of the cotton from becoming engaged in the ournals of therevolving brush. I am aware that metallic fans have been used on theends of a cylindrical brush, in the cotton gin, as described in E.Carvers patent; and I am also aware that brushes have been arrangedaround the periphery of the end of the cylinder, and that such anarrangement was patented by B. D. Gullet, in 1858; but, while I believethat I can prove priority of invention over Gullet, I deem myarrangement essentially different from, and an improvement upon, his; asit combines the advantages of the fans of Carver, with the protectionagainst fire, attained by Gullet. I therefore claim- The brushes on theends of the cylinder, when arranged substantially as above described,for the purpose of preventing the filaments of cotton, or other fibroussubstances, from becoming entangled in the journals, and for preventingaccidents from fire.
